目的 秸秆育苗钵包装容器是一种新型的育苗容器， 已有研究成果中表明该育苗钵包装容器能够提高幼苗的成活率， 但是很少研究该容器的降解情况。方法 以3种不同育苗钵包装容器为研究对象， 通过室内模拟培养试验， 探索在不同水分条件下， 微量元素的降解情况， 揭示了育苗时水分， 施肥情况等对该容器降解速度的影响。结果 试验表明， 70%~80%的含水率能够加速该容器的降解； 在60d培育期间， 前期降解较快， 后期逐减慢。3种秸秆育苗钵包装容器在养分释放方面均表现为C≈N； 降解速率方面表现为C>N。结论 为育苗钵包装容器的制备和降解性能研究提供一定的理论依据。

The packaging container of straw seeding pot is a new seeding container and the existing research results show that the container can improve the survival rate of seedlings, but the degradation properties are rarely reported. This experiment took three different packaging containers of straw seeding pot as the research subjects to explore the degradation of trace elements in different moistures by the laboratory simulation which revealed the influences of water, fertilization and other conditions on degradation rate when seeding. The experiment showed that 70% ~80% moisture contents could accelerate the degradation of seeding container. The degradation rate was high at the early stage and low at the late stage in the 60 days of cultivation period, And the nutrient releases of the three kinds of seeding containers were manifested as C≈N and the rates of degradation were manifested as C>N. This experiment provided certain theoretical reference for researches on preparation and degradation of the packaging container of straw seeding pot.
